introduction: infants born with congenital anomalies demand individualized nutritional evaluations and recommendations. the anatomical changes of neonatal surgical diseases create specific physiological constraints.patients with different congenital anomalies have different nutritional support needs. it is essential to know the exact physiology of these anomalies in order to be able to manage a...

that given here, applies the term pyloric canal to the passage through the pyloric sphincter in X-ray photographs of the stomach (fig. 4) and in the description of the movements of the stomach. Most radiologists still use the terms pyloric antrum or pre-pyloric segment for what is anatomically the pyloric canal, though Shanks (1938) uses the terms pyloric canal and pylorus as synonymous, statin...

In several systems, including some well studied invertebrate "model" preparations, rapid, rhythmic inputs drive slow muscles. In this situation muscle contractions can summate temporally between motor neuron bursts, tonically contract, and low-pass filter broad-band input. We have investigated how the muscles innervated by each motor neuron type of the rapid, rhythmic (cycle period, approximate...

In the isolated stomatogastric nervous system of the lobster Fasus lalandii, the strong modifications of the pyloric motor pattern induced by firing of the single anterior pyloric modulator neurone (APM) are due primarily to modulation by APM activity of the regenerative membrane properties which are responsible for the 'burstiness' of all the pyloric neurones and particularly of the non-pacema...

The hyperpolarization-activated inward cationic current (Ih) is known to regulate the rhythmicity, excitability, and synaptic transmission in heart cells and many types of neurons across a variety of species, including some pyloric and gastric mill neurons in the stomatogastric ganglion (STG) in Cancer borealis and Panulirus interruptus However, little is known about the role of Ih in regulatin...

Pyloric stenosis is defined as an obstruction to gastric emptying due to any cause situated above .he biliary ampulla. This article is concerned with the clinical features, metabolic disorder, assessment and treatment of patients with pyloric stenosis; anatomical narrowing of the pyloric canal without delay in gastric emptying is not considered. In adults, symptoms due to the underlying lesion ...
